यदि \(A=\{1,2,3,4\}\), \(B=\{3,4,5\}\) और \(C=\{4,5,6\}\) है, तो (\(A\cap B\)\cup C) क्या है?
If \(A=\{1,2,3,4\}\), \(B=\{3,4,5\}\), and \(C=\{4,5,6\}\), what is (\(A\cap B\)\cup C)?
Explanation opens after your attempt
A. ( {3,4,5,6} )
Concept
\(A\cap B={3,4}\), and its union with (C) gives ({3,4,5,6}). Do the bracket first.
Why this answer is correct
The correct answer is A. ( {3,4,5,6} ). \(A\cap B={3,4}\), and its union with (C) gives ({3,4,5,6}). Do the bracket first.
Exam Tip
\(A\cap B={3,4}\) है, फिर इसे (C) से मिलाने पर ({3,4,5,6}) मिलता है। कोष्ठक पहले करें।
